摘　　要：结合工程实例,简要介绍挤扩支盘混凝土灌注桩的受力机理、特性及设计方法,并用静载试验结果对设计内容进行验证。结果表明,挤扩支盘桩与普通钻孔灌注桩相比,具有单桩承载力显著提高,节约混凝土,桩身沉降明显减小,对土层地质适应性强,施工方便等优点。Based on project examples, the paper introduced mechanism under stress, trait and design methods of cast - in - site pile with expanded branches and plates and tested it with the static test result. The findings show that compared with common cast - in - site piles, cast - in - site piles with expanded branches and plates have higher capacity of the single pile, save concrete and reduce subsidence of the pile shaft. Furthermore, there are advantages such as strong adaptability and convenient construction.
